files.blobstore.create ApiTemporaryUnavailableError

[Brian G]

For the last several days, AppEngine has been throwing
ApiTemporaryUnavailableError whenever files.blobstore.create() is
called. I am passing no parameters to the create call.

I realize this is an experimental feature; has it been removed from
AppEngine? Is there an alternate method for creating blobs on the fly?

I have a desktop application that uses Microsoft BITS to transfer data
from AppEngine. The only way I could get data of any size to download
using HTTP RANGES (required for BITS) was to serve the data using
blobstore_handlers.BlobstoreDownloadHandler.

The data is retrieved from the datastore, formatted into XML, and
saved in a blob using files.blobstore.create(). The blob is saved and
used for all subsequent requests for matching data.

App name: mcneel_app_store, version 2.

Thanks in advance for your help, my app is dead without this feature
working, and shortly my customers will notice and start screaming.

Futher investigation indicates that this problem started with the release of AppEngine 1.6.5.

I abandoned this API by using the non-experimental blob upload APIs and urlfetch to post the data. It seems to be working much more reliably than files.blobstore.create().

Now I know never to touch an experimental feature :)
